Or has it always??

No, for a bit more than 2 billion years there was nothing more complicated than blue-green alae on the planet. The blue-green culture (pardon the pun) just didn't add much to evolution of the cells.

Evolution was very slow for the first couple billion years because all the change and variation was due to mutation, and mutations are usually bad. After a couple billion years there developed some cells that used sex to shuffle their genes, and then evolution progressed at a faster pace. Still, there was nothing that could even resemble proto-culture until about a half billion years ago. Human culture is only a few tens of thousands of years old with most of it developed in the last 5000 years.
